My son is 13 weeks this week. I think that I have an oversupply. My son often chokes and coughs when he is feeding and I am always full and engorged, especially at night. About 4 weeks ago my son started to sleep 6-7 hours at night and this has left me engorged in the middle of the night and with plugged ducts every other day. For three weeks now I have been feeding the baby on only on breast per feeding. He feeds around every three hours so each breast is being fed on every 6 hours or so. I also started taking Lechithin this week. This new way of feeding seems to be helping during the day but at night each breast is going 8-9 hours since the baby sleeps longer. Do I need to make my blocks longer during the day so each breast is going 9 hours during the day between feedings (each breast used for two feedings before switching) or is this something I just have to give more time and it will level itself out? I still don't feel as though my supply and demand has kicked in, will this happen at some point so I feel less full all the time?
